Lrp blast, we have 2 that my son and myself run, we have changed the standard radio gear,both have brushless in them and rearlly had no problems with them apart from steering blocks stripping threads on my sons car(soon modified with brass inserts) but they are like anything else, treat them correctly and they will be as reliable as any thing else plus you can get carbon shock towers for them and on the LRP part of the forum there is even a guy that runs a carbon chassis which he had made at a reasonable price.
